Comment 13 Michael Nguyen 2021-03-16 16:53:46 UTC
Verified on 4.8.0-0.nightly-2021-03-16-111809.  

Watched `oc get nodes` and `oc get mcp` then ran `oc patch secret -p='{"metadata": {"annotations": {"auth.openshift.io/certificate-not-after": null}}}' kube-apiserver-to-kubelet-signer -n openshift-kube-apiserver-operator`.

Observed node nodes stayed ready and control + compute machine config pools quickly went from Updating to Updated (under 30 seconds).
